I hate to state the obvious but how do they get all the contestants to follow this? I mean they must be hungry as hell. I am sure there are days when they can't follow this but I am curious how the food situation is? Can they eat when they want? Or is it like prison settings where they are given meals at certain times and can not eat otherwise. I am also considering cutting my calories much more then I have been (though not this extreme). How are they not passng out from malnutrition?
You can be very full with low calories. You just have to be eating the right kind of food.
Take broccoli for example. A cup of raw broccoli has 30 calories! Now a lot of people don't like the taste of broccoli, neither did I, until I stopped eating all the other processed crap. When I stopped eating the junk, the real food tasted a heck of a lot better.
I really like using broccoli with salsa instead of chips. YUM.
